Obama never had a congress that was filibuster-proof. The 110th, 111th, 112th, or 113th congress weren't. The 110th was the most favorable but wasn't filibuster proof, least of all under the filibuster rules of the time.

Plus the poster I was responding to specifically made claims about the Republican's policies and what they claimed the Republicans had tried. If the Republicans don't bring up legislation the Democrats cannot be blamed for not voting for it (or Obama for not signing it).
