Why did Roosevelt form the "Bull Moose" Party?

Question

Help me please.

Answer 1

The above answerers are correct in pointing out that TR was unhappy with Taft. But it goes a lot further than that.

Taft strayed from what TR wanted in a lot of areas. He busted trusts based on legal reasons, in that they fit the definition of trust rather than what TR would have done, if they hurt the public. Taft went after J.P. Morgan's steel trust, which offended TR. Morgan, as it turned out, had bailed out the US government in a financial crisis in 1905, and for Taft to go after him was seen by TR as unfair. TR felt the government owed Morgan one.
Another area of contention was over the environment. TR had put millions of acres aside, but Taft's secretary of the Interior, Richard Ballinger, set about selling some of the land to oil and coal and timber companies, offending TR greatly.
Taft, it turned out, was no Progressive. Lots of TR's old buddies pointed out that TR had put Taft in the White House and it was up to TR to get him out.
In 1912, TR decided to run for the Republican Nomination. Back then, there weren't as many primaries, and they didn't go to conventions with every state already nailed down. TR won every primary handily, even Ohio (Taft's home state), and won several by 3 or 4 or 5 times the number of votes Taft got. But at the convention, Taft used the party machinery and pulled strings and won the nomination.
This infuriated TR's supporters. There was cursing and screaming and fistfighting. TR's supporters left the convention chanting "Thou shall not steal". They gathered in a nearby hotel, formed their new party, and ran TR as their candidate.

The key thing is, they tried to get the Republican nomination first, and when that failed, then set up a third party.

hope this helps.

Answer 2

Teddy Roosevelt had originally run for the Republican nomination and was opposed by Taft , the President in 1912. While Roosevelt captured the majority of primaries, Taft had the insiders vote at the convention. While TR felt cheated, he went out and formed the Bull Moose party, a Progressive Republican party who followed his ideals concerning reform, and other Progressive ideals.

Answer 3

Roosevelt had groomed his successor, William Howard Taft, to carry on his political plans and ideals. However, when Taft entered office he strayed dramatically from what Roosevelt expected. Taft was running for reelection as a Republican and Roosevelt formed the Bull-Moose Party to appose him.

Answer 4

IIRC, he was not pleased with the Republican Party platform. He wanted to be more Progressive and his former party was still shaking off the shackles of the "Big Business party" that they put on themselves during the Gilded Age.
