2016 presidential candidates seeking support from the Republican establishment previously faced only one issue, a crowded field vying for the same group of donors and supporters. Now they face two: a crowded field and a disapproving primary base.

According to a December 2015 NBC/WSJ poll of New Hampshire Republican primary voters, establishment candidates have, for the most part, been viewed unfavorably:

In recent news, Ohio state officials told Democratic presidential candidate Martin O’Malley that he could not be on the Democratic primary ballot. The petition to be on the ballot required 1,000 valid signatures from a single county. O’Malley submitted 1,175, but only 772 were considered valid. Both of his fellow Democratic presidential candidates, Hillary Clinton and Bernie Sanders, are on the ballot.

Rasmussen Reports released the results of a new survey Thursday that found that a majority of respondents (56%) say they are less likely to vote for a candidate who uses negative attack ads against his or her election rival(s). Further, 60 percent see a major disparity between TV ads that attack opposing candidates than promote the candidacy of the person running for office.
