Mine is tequila with a bong water chaser. What are you on?
Probably at the same time as everyone else – Democratic, Republican, Whig, what-have-you – who proposed any of the 11,000 other failed Constitutional amendments over the years.
And of those eleven thousand, how many of them were incorporated into a measure that actually passed the House? How many received that level of support from any party?
I have no idea. Feel free to research it and let me know.
Are you disputing that the folks who proposed these amendments were aware of the difficulty inherent in getting the Constitution amended?
The debate has gotten off-track. The question on the table is:
Are both parties are at fault?
The answer is clear: Only the Democrats are to blame.
Recent economic developments make it very clear that only a fiscal stimulus from the government can avoid lingering recession. Yet what stimulus have the Democrats put on the table? Infra-structure development, and propping up retirement funds. 
What the American people want, and what the GOP will give them, are further tax cuts, increased spending on wars, and increasing employment at Homeland Security and prisons. The Demos need to just get out of the way and let the GOP give the American people what they want.
Recent GOP actions may have deepened the economic crisis in the short term, but visionary thinkers should thank the GOP. It is necessary to increase malaise so that Americans will vote correctly in the coming election, and America can get back on track.
