As the Democratic race in Iowa tightens, Vermont Sen. Bernie Sanders is stepping up his political game — with a swanky campaign bus, a newfound eagerness to recite poll numbers, and an increasing tendency to throw political punches at Hillary Clinton.

On Tuesday, he crisscrossed the snow-covered roads of western Iowa in an intense four-city bus tour. Yes, Sanders now has a campaign bus — it's blue, emblazoned with his slogan, "A Future to Believe in." In smaller print, it notes that it was paid for by Bernie 2016, "not the billionaires."

Plenty of politicos and pundits have rationalized Donald Trump's political ascent as the result of his enormous popularity among white working-class voters.

No doubt Trump is well-liked by many college-educated Republicans, but his real strength is among those without a bachelor's degree. In that demographic, most polls show the business-mogul-turned-GOP-presidential-candidate is trouncing his Republican rivals.

Asian-Americans are a bit of a voting paradox. They're the fastest growing minority group in the country, but they're also the least likely to vote.

Take the 2012 election — Asian-Americans voted Democrat in higher numbers than ever before (73 percent cast a ballot for Barack Obama). But they had the lowest voter turnout of any racial group (47 percent).

To try and narrow that discrepancy, a group of Asian-Americans have created the AAPI (Asian American and Pacific Islander) Victory Fund.

When Donald Trump met with a group of black ministers in New York City in November, Stephen Parson, a minister from Richmond, Va., was faithfully in attendance. Then, in December, when Trump spoke at a rally in Manassas, Va., Parson again stood by his side — this time giving him a ringing endorsement.

Florida Sen. Marco Rubio is trying to play up his foreign policy credentials by ripping into some of his Republican rivals. He did not blast any of his opponents directly by name, but in a speech in Hooksett, N.H., Monday morning, Rubio took some veiled shots at Sens. Rand Paul and Ted Cruz.

Rubio questioned their national security qualifications, and he specifically took aim at Cruz for supporting Syrian President Bashar Assad.

Over 25 million Latinos are eligible to vote.

And, each year, that number grows because hundreds of thousands of Latinos turn 18. Hispanics are one of the youngest racial or ethnic groups in the country.

From Ferguson, to Baltimore, to Charleston, racially charged violence and protests dominated much of the news in 2015. While much of the country watched these events unfold, they had the deepest resonance in the cities at the center of them — going beyond the news and filtering into into family living rooms and kitchens.

Bob Vander Plaats, the influential president of the conservative Christian group the Family Leader, is endorsing Texas Sen. Ted Cruz.

"Our goal is to unite conservatives around Ted Cruz," Vander Plaats said Thursday in the rotunda of the Iowa state capitol. "We believe he'll be the nominee to take on and defeat Hillary Clinton."

Vander Plaats said he told Donald Trump on Wednesday that he would not be endorsing him, but that the two remain friendly.
