Former Vice President Joe Biden beats President Donald Trump in a 2020 match-up by 11 points, a new Morning Consult/Politico poll shows.

Forty-six per cent of registered voters surveyed selected Biden, while 35 per cent went for Trump.

However, a generic 'Democratic candidate' does even better, with 48 per cent of respondents saying they wanted a Democrat in the White House next, over the 34 per cent who'd like the nation to stick with Trump.

Morning Consult and Politico's new poll shows both Joe Biden (left) and a generic 'Democratic candidate' getting the best of President Trump in the 2020 election, though the generic Democrat does better

Biden's latest book 'Promise Me, Dad,' was released Tuesday and the former vice president has been making the talk show rounds, appearing with Oprah, and with Ellen and taking over portions of the Today show yesterday.

Pollsters didn't ask respondents questions beyond who they preferred in 2020, but if he did run, Biden's age would likely be a factor.

Biden will be 77 at the time of the next presidential election.

He'll be 78-years-old by the time inauguration rolled around.

However, Trump's age could be a mitigating factor, as the current occupant of the Oval Office will be 74 on election day 2020.

The new Morning Consult/Politico numbers are a stark warning for Trump, as incumbents usually have an edge in the early months of their presidency.

For example, President Obama won or was tied in a theoretical 2012 race in every survey conducted in his first year as president, except one – when he was routed by former Arkansas Gov. Mike Huckabee by one point in a January 2010 poll conducted by Public Policy Polling, a year after his swearing-in.

Two surveys, one in July and one in November 2009 – the equivalent to where in time Trump stands today – had Obama tied with former Massachusetts Gov. Mitt Romney, the Republican he would would eventually compete with.

No Republican was beating Obama outside the margin of error until late October of 2010, when in a CNN poll, Huckabee bested the sitting president by 8 points and Romney beat Obama by 5.

About a week later, Republicans took back the House, gaining 63 seats and taking the gavel away from Democratic Leader Nancy Pelosi to put House Speaker John Boehner, an Ohio Republican, in charge.

Now, with Trump in the White House, polls indicate that Congressional Democratic candidates also have an edge.

The new Morning Consult/Politico poll showed 44 per cent of respondents preferred a generic Democratic candidate, versus 36 per cent who like a Republican better.

Twenty per cent of respondents said they didn't know or had no opinion.
