Former presidential candidate John McCain is now the least popular senator in the country. He's unpopular with Republicans, Democrats and independents alike, according to Public Policy Polling.
He's also unpopular with both parties in his home state of Arizona, meaning that he's doubled his odds of losing his Senate seat in 2016: He could lose the primary to a conservative or the general to a Democrat.
Why is everyone hating on McCain? It's a pretty stunning turnaround from 2008, when he ran for president. Back then McCain was one of America's most popular lawmakers and one of the few Republicans for whom Democrats could stand to vote. He won over 45% of voters.
One reason for the shift is that McCain's politics are now totally out of step with popular opinion. He's running against the libertarian tide of his own party. He's a pro-NSA hawk who'd like to intervene in Syria. He is liberal on immigration reform, an issue that most liberals don't care about and most conservatives violently oppose. And he's conservative on gay marriage, an issue on which most Americans are now liberal.
Plus McCain hasn't done himself any favors by staying in the limelight since 2007. His relentless media appearances mean that people of every political stripe are well aware of his political views, including those they disagree with.
McCain has also fallen victim of dramatically increased partisanship and polarization since 2008. McCain's major selling points were moderation and bipartisanship. Those qualities are now seen as weaknesses by the the most active American voters. Political activists on both sides want lawmakers who represent their own strongly held views - firebrand conservatives like Ted Cruz or ardent liberals like Elizabeth Warren. Instead McCain alienated his party base when he called Cruz and Rand Paul "Wacko Birds" during the 2013 shutdown.
So for conservatives, McCain is a liberal RINO who insulted their rising stars. For liberals, he's the nutcase who tried to inflict Sarah Palin on an unsuspecting nation. No wonder he's unpopular.
