The short answer, of course, is "nothing" - Congress, or the presidency, have been irrelevant ever since the Fed fully took over the US some time in late 2008. Since then, it has been the role of the central printer of the US, working on behalf of the US banking syndicate, to "get to work", and cover up the fact that Congress, its make up, or its decisions, are now inconsequential. Still, there are those whose job is to overanalyze everything, and those, whose ideological persuasion, is to believe that what there is a difference between the "left" and the "right."

One such place is The Hill, which writes that "the midterm-election horserace is into its final furlong — and that means most of the attention of the political world is focused, understandably, on who’s up and who’s down; who will win and who will lose. But if Republicans succeed in their quest to secure a Senate majority on Tuesday, what will really change on Capitol Hill? The answer is “plenty” – both in terms of policy and politics."

We'll agree to disagree, but since someone has to pay attention to the proceedings in the most farcical and polarized, if only for public consumption purposes, Congress in history may as well present what The Hill thinks will happen.

Here are the five areas to watch according to The Hill.

1. Will President Obama’s big achievements be hollowed out?



Republicans say that if they gain control of Congress they will start chipping away at two of the Obama administration’s biggest victories: financial reform and healthcare.



The GOP could well decide against attempting another full repeal of the Affordable Care Act. But its members would probably try to eliminate the much-discussed medical device tax. They might also look at nixing the employer mandate.



The Dodd-Frank financial law is high on the hitlist of GOP lawmakers. They want to ease capital requirements for large insurance companies, create both a board of directors and a new inspector-general position for the Consumer Financial Protection Bureau, and streamline a process for banks deemed too big to fail.



More generally, Republicans have made it clear that Obama’s regulatory agenda is a prime target.



With control over the budget and appropriations process, Republicans could cut off funding that is needed to implement or enforce regulations — including the EPA’s carbon-pollution standards for power plants, which form a big piece of the president's climate agenda.



The GOP will also probably ramp up efforts to push through the Keystone XL pipeline and expand natural-gas exports.



2. Senate confirmations: The battlefield tilts



A GOP-controlled Senate will make it even tougher for Obama to confirm nominees, a process that hasn’t exactly been plain sailing even with Democrats in charge.



Although Supreme Court Justice Ruth Bader Ginsburg has said she is staying put, it remains plausible that Obama could be faced with a third chance to put his stamp on the court. Republicans would find it much easier to block his choice if they held the majority in the Senate.



Obama will also nominate a replacement for retiring Attorney General Eric Holder, and the confirmation process will likely be fraught whomever he chooses.



Obama also isn’t like to face any shortage of executive branch, ambassador and federal judicial nominations in his final two years in office. They will all need Senate confirmation.



3. Obama to stock up on veto pens



Obama has had to pick up his veto pen on just two occasions since he took office in 2009, largely because Democrats have controlled at least one chamber of Congress throughout that time.



He will need to check he has a plentiful supply of ink if Republicans take the Senate majority. He can expect to spend his final two years using his veto to protect earlier legislative victories, rather than seriously attempting to rack up new ones.



There is some chance of bipartisan progress on issue such as immigration reform and global trade deals. But it also seems likely that Obama will need to rely on executive action if he wants to pursue many of his priorities.



4. More Benghazi, more anti-ISIS action



If Republicans take over the Senate, Sen. John McCain (R-Ariz.) will take the gavel at the Armed Services Committee. He is almost certain to turn the spotlight back onto the Obama administration’s missteps in Benghazi — especially the ones that Republicans say were committed by Hillary Clinton, who was secretary of State at the time.



Congressional Republican make little secret of the fact that they believe the controversy could hurt Clinton’s chances of winning the White House in 2016. Senate control would ensure they could keep it high up on the news agenda.



Republicans also are likely to push for a more aggressive U.S. response to the militants of the Islamic State in Iraq and Syria, or ISIS. They have long argued that the Obama administration isn’t being aggressive enough in that fight.



While their push probably won’t come in the form of asking for more U.S. troops in Iraq and Syria, Republicans insist that the United States ought to do more to quell terrorist threats in the region.



Republicans are faced also with a slew of expiring bills but none more important to national security than an NSA surveillance reauthorization.



It will be up to the GOP to push a bill across the finish line, just as 2016 presidential contenders ramp up their campaigns. Many national security experts have argued that letting the current law expire would be disastrous.



5. 2016: The future starts now



Whoever wins and loses on Tuesday night, much of the political world will turn its focus to 2016 as soon as dawn breaks on Wednesday.



If the GOP controls both chambers in the new Congress, its leaders will take every step over the following two years with an acute appreciation of how their moves might affect the 2016 race for the White House.



They will have to walk a fine line: They will want to make Democrats take tough votes while also helping those within their own ranks who might seek the Oval Office. GOP Sens. Rand Paul (Ky.), Ted Cruz (Texas), Marco Rubio (Fla.) and Rob Portman (Ohio) have all had their names bandied about as 2016 hopefuls.



There will also be the concerns of those senators seeking reelection in 2016 to consider. Some centrist Republicans may seek to forge new relationships with Democrats in order to advance legislation they deem important to their reelection hopes.

And while we appreciate The Hill's enthusiasm, we are far more interested in the take of the one company that in most people's opinions, comes closest to actually running not only the Fed, but the US itself: Goldman Sachs. Here is what 4 of Goldman's strategists and analysts think will happen after Tuesday's takeover of the Senate by the GOP.

Alec Phillips, GS US political economist

"A Republican Senate majority would likely lead to an incremental uptick in legislative activity and increased risk around fiscal deadlines.”

Aleksandar Timcenko, GS strategist

"Since 1950, S&P 500 performance following midterm elections has averaged 17% – substantially better than average returns of 9% per year.”

Matthew Borsch, GS US healthcare analyst

"Gridlock or compromise on healthcare policy is possible should Republicans win the Senate, with the former better for hospitals and provider firms and the latter for managed care and medical devices.”

Noah Poponak, GS US defense analyst

"Neither outcome for the Senate makes a particular defense spending trajectory more likely, but sequestration puts a floor under downside risk for the sector.”"

Oddly enough, virtually nobody, when asked what would change if party X takes over party Y in the [House|Senate|Presidency], has replied "nothing." Which is precisely why it is the right answer.
