In the last few weeks, the Romney campaign saw it's numbers start dwindling from what would have been a close election into a run away win for Obama.
This should be a cakewalk election for whoever the Republican nominee is considering that unemployment is still relatively high, but the Republicans may have cut their own feet. In 2010, after the party won the House of Representatives their leaders were no so quiet about declaring their intentions of doing whatever it took to make Obama a one term president. People heard this and began to pay attention. So, now, when Romney and other Republicans attempt to damage Obama by talking about the economy and how it is completely his fault, people remembered what they had said previously.
After months (nearly a year) of some of the most negative campaigning against his fellow Republicans and then against Obama, Romney took offense to an Obama Super PAC (you know one of those organizations that are not attached officially to the campaigns but can get all kinds of money from businesses which Romney supports) ad. The ad was, of course, an attack ad, but nothing the Romney campaign or his Super PACs had not done previously. Naturally, the "liberal" media paid little attention when Romney was the one making the attacks, but when one ad popped up in support of the Obama, suddenly the campaign had grown far too toxic. Romney took offense to the ad and demanded an apology. Then in a very strange twist touted that if the family in the ad had been in Romneycare nothing bad would have happened (Romneycare being the basis for most of Obamacare, which Romney now opposes (he initially supported it, it was an odd claim).
So with his campaign struggling and starting to slip further behind Obama, despite the millions being spent on the campaign, Romney finally announced his Vice Presidential pick, Paul Ryan.
Paul Ryan's big mark on politics (actually his own mark after being in Congress for over a decade) is his plan for a much smaller government and a balanced budget. His plan, lacking any real numbers really only proposes cutting government agencies and ending Medicare.
For Romney who was already well behind in support in Latinos and women, picked a man whose plan will take away a program that many of the elderly depend on, a program that they paid into their entire working lives.
To this point Romney has received no bounce from his pick of Ryan, which really is no surprise. The only candidate that received any real bounce from announcing a vice president in recent history was Clinton who saw his polling jump by double digits. Even Obama only saw a one point bump from his announcement in 2008.
Romney has long been seen as a candidate that cannot decide which side of a political argument he actually stands. His entire campaign has been filled with moments of him being for something before being against it and then in some cases being for it again. Just in his vice presidential pick, he initially favored Ryan's plan, then backtracked and said that he did not really support the plan, before coming full circle and completely supporting Ryan's plan. That was all within a week.
If the election were held today (actually I hate that phrase so let's go with if the numbers stay where they are) Obama will win in convincing fashion. He would either win by over 100 electoral votes or just under that many. It is not a landslide in the classic sense, but in today's every dividing political spectrum that would be quite the accomplishment.
