X is for the XTRAORDINARY PEOPLE PARTY - an offshoot of the charity, XTRAORDINARY PEOPLE, that campaigns for the UK's estimated ten million dyslexics.
Its founder and leader, Kate Griggs, is standing against Education Secretary, Ruth Kelly.
More fundamentally, X is quite simply for X - the symbol of many of the democratic deficiencies of our present electoral system: the high abstention rates, turnout disincentives, wasted votes and tactical voting disputes.
All arise from the fact that, as electors, our sole task is to place that single X against a single party and/or candidate.
The two are indistinguishable: we cannot have one without the other.
The party/candidate with the most votes wins, even if that number is nowhere near an actual majority, as in half of all GB constituencies in 2001. In such cases, more than half the electors will have wasted their votes, having backed one of the losers.
But equally wasted are those votes giving the winner an unnecessary surplus of more than one.
Add those figures together and about 70 per cent of us voting on Thursday will effectively waste our votes.
For all the contribution we make to the result, we might as well stay at home - like the many who will do just that, knowing full well, having been largely ignored by all party canvassers, that their constituency was safe for one major party or another. And on Friday we will probably have another oneparty government.
Proportional electoral systems would avoid that latter outcome, and preference systems would give us all more incentive to participate, by giving us choices - not just that single X.
The Alternative Vote system in our existing single-member constituencies would enable us to rank candidates in order of preference - 1,2,3 etc - with the winner having to obtain an actual majority, if necessary using our second and third preference votes.
The Single Transferable Vote in multi-member constituencies would give more choice still, between candidates from the same party, and a much greater likelihood of our electing at least one candidate from our preferred party.
Y is for the YOUTH VOTE - always hard to mobilise, even under a much voter-friendlier system. Polls suggest that those young people who do vote this time will do so quite distinctively, with over half supporting Labour and more favouring the Lib Dems than the Conservatives.
They are relatively more concerned, not surprisingly, with education; also with taxation and public services, and with Iraq, as shown in the Birmingham Post's recent teenager canvass in Sparkbrook & Small Heath.
They give relatively less priority to the economy, health and immigration. They also (or at least my students) watch more daytime TV, including Richard and Judy's YOU SAY, WE PAY, in which celebrities guess the identity of people and objects to win money for viewers.
If, like Tony Blair, you fail repeatedly, despite much assistance, to identify such items as a guinea pig and a courgette, you've almost certainly lost the vote of the impoverished viewer and probably much of your credibility with your target female audience as a whole.
We end this A to Z series with the topic that launched the whole election, postal voting.
Z is for ZANU NEW LABOUR PF, the initials standing, of course, for Postal Fraud.
It was one of the appellations swiftly invented by election bloggers for Labour following Birmingham's election trial - another being, almost inevitably, Banana Republicans, after the judge's condemnation of a system "that would disgrace a banana republic".
For that quote alone, our city will have its footnote in British electoral history.
