Who should fear Marco Rubio the most?

Lately we have learned from the New York Times two facts that seemingly disqualify Marco Rubio from the presidency. One, He is at best an average driver and two, he may not be rich enough to be president. First, the Times jabbed with Rubios on the Road Have Drawn Unwanted Attention which revealed the sad and sickening fact that the junior senator had accumulated 4, yes 4 speeding tickets over the course of 18 years. Then came the right cross with Struggles With Finances Track Marco Rubio’s Career, a startling tell all, wherein the public learned the man who would be president had struggled to pay off his student debt.
In a USA Today post Glenn Reynolds noted that the research into the Rubio's nefarious driving record was done by the left leaning PAC, American Bridge. The Times denied that AB was the source and it may be telling the truth if not the whole truth.
The Times was not the first publication to delve into Rubio's finances. It started before Rubio got to the senate. See this post in the Tampa Bay Times and learn that the father of 4 "  he had $30,000 in "assorted credit and retail debt" (as described on his financial disclosure form) and in 2001 listed $165,000 in loans from the University of Florida and University of Miami Law School."
News that Rubio is on the ragged edged of pecuniary decency seems to be a popular theme. Before the Times story Business Insider attempted to breath new life into this dying theme with Marco Rubio has a 'big money' problem which is essentially a rewrite of the Tampa Bay Times story where we learn that Rubio got a haircut on his Republican Party credit card back in 2010. The staid online publication, Mother Jones, an institution so successful that it operates as a 501-C3 got into the act with Marco Rubio has a 'big money' problem noting "Republican Party was never reimbursed for, including $68.33 for "beverages" and a "meal" from a liquor store near his West Miami home, $765 from Apple's online store for "computer supplies," and $1,024 in payments to a Tallahassee property manager for personal business. Since Rubio has not released his credit card records from 2005 to 2007, it's unknown how he used the card during those years".
Oh no! He stiffed the Florida GOP for $68.33 ten years ago. Put in context with Rubio's scandals Hillary looks like a saint.
Like most right leaning bloggers and pundits I credited the Clinton camp for this assault on Rubio until the following tweet caught my eye.

To whom does Marco Rubio pose a threat in the near term? Hillary Clinton or Jeb Bush? Where are the Time's phony scandals relative to Rand Paul and Scott Walker? Who will be Jeb Bush's chief rival in the first big state primary, Florida?
This post from the Advocate, a LGBT group turned up in a Google search and caught my attention. Forget the source this isn't about straight or gay.

America Rising super PAC co-founder Tim Miller will likely head up communications for Republican presidential hopeful Jeb Bush, as the former Florida governor ramps up his bid for the nomination in 2016.
Miller, one of the most prominent gay Republicans in Washington politics, has worked on numerous GOP campaigns, including John Moccasin's in 2008, and Jon Huntsman's campaign in 2012, followed by Mitt Romney's campaign that year. According to Politico, Miller will act as a senior advisor to Bush's Right to Rise PAC, but will likely become Bush's communications director if he does officially launch a campaign.
"Miller is an aggressive, younger operative who can be expected to inject a pugilistic style into Bush’s high command," Politico's Mike Allen says.

Is this where the body is buried? Are the attacks on Rubio being orchestrated by the Bush camp? Just asking.
