Producer Will Rabbe of The Chris Matthews Show, a syndicated public-affairs program that runs on Sundays, took a look back at the debates and, for fun, kept track of the color ties presidential candidates wore -- and what patterns may have emerged.

Does it matter whether a candidate wears a red-or-blue necktie in the presidential debates?

Well, since the first televised in color in 1976, there have been a total of 22 Presidential debates, each with two major candidates. Therefore, there have been a total of 44 ties worn in debates over the last 9 elections.

Of those 44, a candidate has chosen to wear a red tie 30 times, a blue tie only seven times and a tie that is both colors or neither a total of seven times as well. (We’ll call this “other”).

Red has been the go-to choice for most candidates by a large margin -- but what’s more interesting is how infrequently a candidate wears a blue tie. (George W. Bush, from a party known for red, wore blue most often).

The “other” category, which includes ties that are both colors, such as blue and red striped in equal ratios, and ties that are neither color, such as grey or brown, are worn 16% of the time. 

There is obviously no correlation between a candidate’s choice of tie and their rate of success (unless you’re willing to delve into the subconscious preferences of the audience), but this begs the question: what color has most often been worn by a winner?

If you count the number of times the individual color has been worn by the eventual winner, divided by how many times the color has been worn in total, the results are counter-intuitive: a candidate who has worn red has won only won 13 of 30 times, giving the tie a mere 43 percent success rate.

Candidates who have worn a blue tie won four out of seven times, a rate of 57 percent, and a candidate who has worn “both/neither” has won the most, in five of seven instances, with a success rate of 71 percent.

The most notable candidates who fall into this “other” category? Reagan in 1980 wore a brown tie; Clinton was partial to striped ties in 1992; and Obama in 2008, who dared to wear a grey tie in the second debate.

Before there was the controversial Sarah Palin pick in 2008, there was Thomas Eagleton, George McGovern’s ill-fated selection in 1972. The Eagleton affair, in fact, ultimately changed how vice-presidential running mates are now made.

With political watchers on veepstakes alert for Mitt Romney’s eventual VP pick, below a mini-documentary on the Eagleton affair.

A little backstory: When McGovern arrived at the Democratic convention in Miami during the summer of '72, his campaign priority was to fend off rival Hubert Humphrey's last-ditch attempt to win the nomination through an obscure rule change. Picking a running mate was relegated to the backburner. After officially gaining the nod, McGovern was left with only an hour and a half to choose a No. 2 -- and he hastily settled on Sen. Thomas Eagleton (D-MO), a man with whom McGovern had only spoken twice.

"Vetting" the candidate was an afterthought, a decision that came to exemplify VP selection gone bad.
