He's saying things that need saying, but he is more of a problem than anything else.
There is no way in hell the Democrats can win enough votes to retain the White house. The fact that an asshole socialist like Bernie Sanders is their "serious" candidate proves that they know it.
Hillary is a non-entity, she spent 16 years between Bill's election and Bush's 2nd term campaigning and could not even win her own party against a Muslim nobody ever heard of. And during the last 8 years she has done such sterling work that she had to claim a brain injury to get out of her job as Sec State, and may still wind up in jail. Hillary's only support is from the media.
The only hope the Democrats have is for the Republicans to shoot themselves in the foot again with a POS loser like McCain in '08. The best way to aid this is to get so many people in the race that the dumb bastards who actually get off their lazy asses to get to the polls get lost reading the list.
They have made a good start with RINO scumbags like Christie, Bush, (the favorites of the left wing media who want the Dems to win) Lindsay Graham and a few others, Then there are the nobodies looking for name recognition, Bobby Jindal is by far the best of this group, but does not have the name recognition needed.
There are really only 2 viable candidates, Cruz and Walker are the best for the job, Perry became a piece of shit like Rubio when he attacked Trumps comments on wet backs. He purposely misrepresented what Trump said, referring to "Mexicans" instead of "illegal aliens" as Trump did.
Trump is a former Democrat who is in this race as the sliest of spoilers, and his threat of a 3rd party run proves he actually sucks.
The ONLY time a 3rd party won the US presidency was in 1860 when the Democrats were so badly split they ran 2 opposed candidates.
Remember Ross Perot ?
A 3rd party run by an inappropriately experienced Will do nothing but take votes away from what ever candidate the Republicans select.
Rather than following the path of proven failure, the best bet is to fight tooth and nail to take back the party that actually has a hope of winning from the RINO's.
