Conventional wisdom in presidential politics long relied on the “lane theory” to game out how a winning candidate could capture their party’s nomination by appealing to a certain specific subset of voters. If that theory still holds, putative 2028 Democratic candidate Rahm Emanuel has an early advantage — in the bike lane.Emanuel, on June 5, took the bicycle lane around New Hampshire as part of a three-day tour of the early voting state, making the longtime Democratic official one of the earliest to openly talk up a prospective 2028 White House bid in what’s expected to be a crowded 2028 presidential primary field. A group ranging from likely candidates such as Govs. Gavin Newsom (CA) and Josh Shapiro (PA), to Democrats who have dipped their toes into presidential primary waters but haven’t been as visible.One thing about the still-forming field is clear — it will be full of candidates brimming with denunciation and harsh criticism of President Donald Trump, a reviled figure over his two nonconsecutive terms (and in between). Except for Emanuel, at least to an extent. His New Hampshire bike trip aimed to announce and promote an array of policy positions, not just spew hatred against Trump.
