Obama chose Joe Biden, a powerful and seasoned liberal senator, as vice presidential mate, to cover his own glaring deficiency in anything political. Biden is a two-times loser for presidential nomination. In 2007, Biden went on the record saying that Obama is not ready for presidency.
Sen. Biden, a Catholic, urged the US Administration to arm Bosnian Muslims in Yugoslavia. In 2001, Biden sought a diplomatic solution with Saddam. He supports breaking Iraq into Sunni-Shia-Kurd enclaves. which would lead to Iran’s expansion. Overall, Biden is a dangerous case of an inconsistent hawk who long for justice for all and is involved with Muslims. His Catholic affiliation, traditionally a domain of anti-Semitism in America, makes him still worse for Israel.
Obama might not gain many votes by bringing in a Catholic.
