Well in the case of Obama, his blaming the Republicans for killing immigration reform in Congress is 100% accurate. The Senate passed a bipartisan bill 17 months ago but the Republicans refused to come up with a bill of their own, or even to hold hearings on the Senate bill.

The same is true for healthcare; the Republicans refuse to come up with an alternative to Obamacare.

I would not underestimate Lapid. There is nothing that voters like more than tax cuts and he is promising non-charedi voters a big one. He went from 12 MKs to 19 in the last week of the last election and that could easily recur again with some well timed charedi bashing. (Promises of irresponsible tax cuts and bashing of people who receive government benefits work in American elections and Lapid knows this.) And Rivlin will probably give either Lapid or the Labor leader (presumably Herzog) the first chance to form a government because Rivlin (correctly) sees the Jewish state bill as being a total public relations disaster for Israel and will do what he can to prevent a supporter from becoming PM.

sounds like a certain president blaming the other party
