Sen. Rand Paul's presidential campaign has a new strategy since last Thursday's GOP debate: Go after Donald Trump, and don't let up.
On Monday, Paul went as far as to hold a conference call with reporters for the explicit purpose of trash-talking Trump.
Paul started out talking about how he got his start in politics with the tea party, an antiestablishment wing of the Republican Party aimed at primarying candidates who were not true conservatives. Paul said conservatives should doubt Trump's sincerity, given Trump's past moderate views on issues like health care and abortion.
In an anti-Trump column Paul wrote for IJ Review Sunday night, he sounded completely baffled by Trump's popularity among Republicans:
No conservative in America supports a single-payer government-run healthcare system, and yet around 25 percent of Republicans seem to favor Trump. How can this be possible? How can a quarter of the GOP support a guy who was a Republican, then an Independent, then a Democrat, and then a Republican again?
The stark reality for Paul is that, while Trump continues to surge in the polls, his own campaign is lagging. And while it's still very early — we're still almost six months out from the Iowa caucuses — Paul clearly considers Trump a threat to the credibility of his own campaign.
