Does the reclassification of a felony drug possession conviction as a misdemeanor affect recidivist enhancements?

Proposition 47 ( 1170.18), enacted by the electorate in November 2014, reclassified certain felony drug possession offenses as misdemeanors. (People v. Lynall (2015) 233 Cal.App.4th 1102, 1108; see 1170.18, subd. (i).) It also created a mechanism whereby a person convicted of such an offense, who had already completed his sentence, could have the conviction redesignated as a misdemeanor. ( 1170.18, subds. (f) & (g).) Although Proposition 47 does not directly address how redesignation of a felony conviction to a misdemeanor affects recidivist enhancements based on the conviction at issue, section 1170.18, subdivision (k) specifies that any "felony conviction that is ... designated as a misdemeanor ... shall be considered a misdemeanor for all purposes, except [for purposes of firearm possession]."
