GOP

Front-runner Donald Trump delivered a broadside against competitor Ted Cruz, telling thousands in Las Vegas he thinks the Texas senator "is sick."

The state party called for citizenship for people living in the country illegally, Republicans fell in line behind their popular Hispanic governor, Brian Sandoval, and the GOP swept the 2014 elections while hardly discussing the issue.

Donald Trump has repeated inaccurate and racially charged crime statistics, reposted pledges of support from white supremacists and retweeted dubious questions about the citizenship of his presidential rivals to an online following of more than 6 million people on Twitter alone.

Trump, the winner in two of the first three states in the presidential primary season, has long been laying the groundwork for more victories in March, when two dozen states go to the polls, new campaign finance reports show.

When the calendar turns to March in this year of the irate voter, the first wave of congressional Republicans will find out whether they have their very own Dave Brat waiting for them.

Jeff Deminski says: The true definition of a hypocrite. Time and time again, Trump's questioned Barack Obama's Christianity.

Jeb Bush, John Kasich and Marco Rubio are locked in a high-stakes political chess match in South Carolina, strategically moving money and other campaign resources around in a bid to pull ahead in the Republican primary race -- or at least keep their campaigns afloat if they don't.

Despite a distinct lack of support from Senate colleagues -- not one single endorsement -- the Republican presidential candidate and freshman Texas senator has a small but loyal group of supporters in the House who are flying to rallies, meeting with voters and trying to convince the electorate that he's not such a bad guy.

Senate Republicans united behind Majority Leader Mitch McConnell in insisting that President Barack Obama's successor fill the Supreme Court vacancy created by Justice Antonin Scalia's death.

Ted Cruz has always talked about the Supreme Court as a candidate for president, but it's become the new focal point of his White House bid following the weekend death of Justice Antonin Scalia.
