I am convinced that the remainder of President Obama's term will be peppered

10. Manny again avoids your point

Yes, Lyndon Johnson did not operate in the same environment we have today. The 88th and 89th Congresses that sat between 1963 and 1967 were overwhelmingly Democratic in both houses when Johnson's signature legislations were passed. Which is not to say the Democrats were overwhelmingly liberal. (But remember, Republicans were also not overwhelmingly conservative.)

Here's the deal (using figures from ends of these terms, rather than beginnings, which reflect lower numbers of Democrats in each case):

88th Congress (Jan 63-Jan 65):
Senate: 65 Democrats, 35 Republicans -- a filibuster-proof majority.
House: 255 Democrats, 177 Republicans

89th Congress (Jan 65-Jan 67)
Senate: 67 Democrats, 33 Republicans -- another filibuster-proof majority
House 289 Democrrats, 136 Republicans

Compare that to Obama's Congresses: the very barest of Democratic majorities in the Senate, but never one that has been filibuster-proof (except for perhaps 2 months at the beginning of his term). An overwhelmingly Republican House that has blocked even what the Senate has managed to eke out with Republican intransigence.
