Below is the transcript of Biden's comments to the Senate. Notice the date. Notice the color of his hair in the video, and his somewhat youthful appearance. Hmm... posting a video of his comments from almost 30 years ago. Talk about irrelevance. 
“When I argued that we should freeze federal spending, I meant Social Security as well,” he told the Senate in 1995. “I meant Medicare and Medicaid. I meant veterans’ benefits. I meant every single solitary thing in the government. And I not only tried it once, I tried it twice, I tried it a third time, and I tried it a fourth time.” (A freeze would have reduced the amount that would be paid out, cutting the program’s benefit.)
"What Biden was expressing was a common sentiment among the centrist faction of the party in the 1980s and ’90s — the belief that old tax-and-spend liberals were out, and that a type of “New Democrat” was needed, one who understood the necessity of fiscal restraint. Cutting spending was the only way, he argued, to salvage what was left of the Great Society and New Deal. The mentality of Biden-style Democrats — that the best the party could do was play defense — was dominant for a generation; it’s now being fundamentally challenged not just in the presidential campaign but in congressional primaries across the country."
Can't have Democrats who understand the necessity of fiscal restraint.
1. His comments in context are that the government is out of control on spending and cuts are needed in every aspect. Not picking and choosing. Nothing gets done when everyone gets to exempt their cash cow.
2. He has evolved and has NOT tried to cut those programs. They've seen an increase as they normally would
3. Republicans showing indignation over fiscal responsibility concerns is hilarious.
