[Let me help you out: A) DREAM Act was introduced in 2001.]
Where did I claim that it wasn't originally introduced in 2001?  In fact, it was explicitly because it failed in Congress in 2001 that I stated "re-introduced."  I fail to see where you can rationally claim I was wrong when you support my refutation that Obama spent years, arguably years more, on immigration reform than the ACA.  Did you perhaps misread what I actually stated, ie. "re-introduced" as "introduced?"  If your "help" is based upon misreading or missing important context you aren't being very helpful.
[ACA was already law in his 2nd year of office.]
Uh-huh.  What are you trying to communicate here?  The point I raised was not about which one came first but refuting the idiotic claim that Obama didn't spend time on immigration reform, or as I directly quoted, "he should have spent time changing [immigration law]."  I don't see how this second point is related at all.
