Donald Trump says that former senator Scott Brown, one of the most liberal Republicans, would make a great vice president .

"You know what? He's central casting," Trump replied, nodding. "Look at that guy! He's central casting! A great guy and a beautiful wife and a great family. So important!"

So who is Scott Brown? First of all, Scott Brown is a big loser. He filled the partial term of Teddy Kennedy and was defeated for re-election in Massachusetts. Then he carpetbagged over to New Hampshire and lost a Senate race there. It's inconceivable that Trump would call a two-time loser great VP material.

But even more, Scott Brown is extremely liberal:

Brown does not support President Obama's health care reform plan in its current form as approved by the Democratic-led House and Senate. [But] Brown supported the 2006 Massachusetts health care reform, which requires all residents to have health insurance, with a state-subsidized plan created for those who cannot afford to insure themselves. Brown refers to the currently legalized same-sex marriage in New Hampshire as a settled issue, which he does not wish to change. Brown has said he personally believes marriage is between a man and a woman, but would still oppose a constitutional amendment banning gay marriage. He is in favor of civil unions. Brown has stated that Roe v. Wade is settled law and is self-described as pro-choice.

Why would Trump, who claims he has given up his New York values-based support for partial-birth abortion to become pro-life, consider a man for VP who is pro-abortion and so liberal on so many other issues?

This is especially worrisome because Trump will have the opportunity, if elected president, to make several Supreme Court picks. What if he picks liberals for those, too? It was a bit unnerving when he said his sister, who is an extremely liberal judge, would be a "phenomenal" Supreme Court pick.

Trump is basically a liberal, except possibly on the issue of immigration. (I say possibly because we cannot know until we see how many "good ones" are invited to return in an expedited fashion.) He can't be a first choice for any sane conservative.
