WI: Charles Evan Hughes accepted the Republican Vice Presidential nomination in 1908?

Just found this on wikipedia and it seemed like a interesting enough POD, so what if Hughes said "Yes" instead of running for Govenor of New York in 1908 so its Taft/Hughes (R) vs Bryan/Kern (D) in the Presidential election.

Who wins? How is history effected?
 
Taft/Hughes would have won in 1908 as did Taft/Sherman in OTL.

Hughes was a progressive and Theodore Roosevelt (TR) was his mentor. In this article - http://www.historycooperative.org/journals/lhr/24.1/henretta.html - in the last sentence in Section III. A Progressive Governor Hughes is described as a
A progressive reformer like his mentor Theodore Roosevelt
.
However if Taft had decided not to run for re-election in 1912, then Hughes would most probably have won the Republican Presidential nomination in 1912. TR believed that he was unfairly denied the Republican nomination in 1912. If Hughes had won the majority of the Republican primaries, then presumably TR would have endorsed him as the party's candidate for President, and the Progressive Party would not have been formed. Therefore with a united Republican Party, Hughes would probably have defeated Woodrow Wilson and been elected President.

Presumably he would have sought re-election in 1916, and considering that he lost narrowly to Wilson, would probably have won, assuming that he had kept the United States neutral in the First World War.

But if TR had won a majority of the Republican primaries, and subsequent events were as in OTL, with him as the Progressive Party candidate, Wilson would still have won the election, though Hughes might have won New York instead of Wilson.
