What Democrat president had a Republican vice president?
nothing..if a democrat president wins and a republican vice-president wins but came from the other parties,it is nothing to do.
Can there be a democrat elected for president and a republican as vice or do the parties have to be the same?
If you are asking about the United States, in 2008, the Democratic candidate for Vice President was Joseph Biden, and the Republican was Sarah Palin. In 2012, the Democrat was again Mr. Biden, and the Republican was Paul Ryan. Since Barack Obama (Democrat) won both times, Joe Biden will serve his second term as Vice President. (Mr. Biden was a U.S. senator from Delaware prior to being chosen as Barack Obama's vice president.)
Andrew Johnson was the Republican nominees for vice president in 1864, but had always been a Democrat and returned to the Democrats in 1868. Ronald Reagan was a Democrat as a young man. He became a Republican by the time he actually ran for office. He said he did not leave the Democrats, but rather they left him.
In a way this is what happened in 1912. Former President Theodore Roosevelt, who was elected as a Republican Vice President in 1900 and as a Republican President in 1904, tried to get the nomination in 1912, but when he failed to get it, he ran as a third party candidate against the incumbent Republican president William Howard Taft. Both were defeated by Democrat Woodrow Wilson.
No. The way our voting is set up, a vote for a republican president isautomatically a vote for the republican vice-president. To think of it in another way, we don't even vote for vice-president. We only vote for president and that candidate's choice for vice-president automatically becomes vice-president if that candidate wins the presidential election.
