You guys, the delegate results tonight are fairly unimportant, this is huge for Clinton, that much is obvious no matter who you support, she's not only not out of it, she's neck and neck and heading into territory very favorable to her.
You are right and wrong. Both are important.
Clinton has, of course, shown viability. She will go on - and rightly so. 2% swing in Texas, even if it weren't significant in delegates, and she'd be much closer to being out of the race. PV victory is important.
Still, the delegate count is also hugely important: there is just too little left. In order to win the convention she'd have either to win with huge margins in remaining state races, or somehow pursuade the bulk of the remaining superdelegate to vote for her. There are just not enough of big states left, period. The laws of arithmetic are getting pretty bad for her.
Still, today is, unquestionably, her day: she survived to give another fight. She is still a heavy underdog, though.
