NoAlternate Answer:Yes, but it is better to use your Mexican Passport. If he doesn't have one, he should get one for this and other purposes. About a dozen US states accept the matricula consular as valid photo ID, including Washington, which also permits same-sex marriages. Even outside of these states, you could probably get the marriage license using the matricula consular alone, but it would be better if you could bring a birth certificate. If you are thinking that you need the matricula consular to prove residence or legal address ... don't worry about it. You don't need to prove where you live to get a marriage license. Foreigners are allowed to get married in the U.S. You don't need to try to appear like a citizen.
If this is the only ID you have, then it is better than nothing. You should invest in a (foreign) passport, however, and try to obtain a copy of your birth certificate. These are much better forms of ID. The one advantage that the matricula consular has is that it shows the address of your US residence.

Some states (about 13) will issue a drivers license or "non-drivers license" to a resident with no legal immigration status. Many of these will accept a matricula consular as part of your identification, but I do not believe it is sufficient on its own.
No. You must present a valid passport from the country of which you are a citizen (whichever country that may be) in order to board an international flight. US Passport cards, drivers licenses, municipal IDs and matriculas consulares are not acceptable for that purpose.
