His time is long gone. He will be 74 years old in November, 2016. Richard Nixon was President when he got to the Senate.(Nixon resigned in 1974.)
While the Senate has had older Senators, they are 1 of 100. There's only 1 President. Ronald Reagan, the oldestPresident to be inaugurated, was 73 when was sworn in for his second term. Biden will be three years older. Even should he be elected, he'd almost certainly be a one term President. He'd turn 84 before his second term was up, and no one wants a President in his 80's.
His age is the easiest reason to overlook him. The real reason is his record on crime.
I have consistently opposed Crime Warrior In Chief Joe Biden on this site since 2003. (All posts are accumulated here.) Pick any drug law you don't like in the last 25 years, and you'll find he's responsible. If he runs, it will be the first time I sit out a presidential election. He will never get my vote.
Joe Biden has been trying to run for President since 1988 (His bid was torpedoed by his plagiarizing speeches of others. It was hardly a one time occurrence, it was a practice that dated back to his law school days). He also embellished (at best) details of his life.
The sheer number and extent of Biden's fibs, distortions, and plagiarisms struck many observers at the time as worrisome, to say the least. While a media feeding frenzy (a term popularized in the 1988 campaign) always creates an unseemly air of hysteria, Biden deserved the scrutiny he received. Quitting the race was the right thing to do.
Even in 2012, he hadn't changed his overly pro-law enforcement and drug warrior views. In Mexico, he said the Obama-Biden Administration would never legalize drugs and are requesting more money for the war on drugs in Central America:
Biden said the U.S. has provided about $361 million in anti-crime aid under the Central America Regional Security Initiative, but leaders in the region called that insufficient. Biden said the administration is asking more from congress.
Biden could care less about pleasing progressives. It's the Republican vote he'll pander to. He acknowledged this strategy in 2008.
The only crime bill we need now is a three strikes law that keeps Joe Biden from running for President for the third time.
