Your strategy has been played too many times to have any credibility at all. When will the time be? The sequester? Budget negotiatons? The next cabinet secretary? The next Supreme Court appointee? People who say this isn't the right issue really mean they don't want to face up to the problem for fear of blowback by liberals.
Reminds me of the "Nuclear option". The Republican leadership decided not to pursue it after the 2004 election because they wanted to wait for the "Right Time and the Right Issue". Turns out when he needed to use it he no longer had the votes to pass it.
